SVG Fundamentals
This example demonstrates fundamental SVG shapes: circles, a rectangle, and a line, each styled with fills, strokes, and stroke widths directly in markup. Rendered in a static 960-by-500 SVG canvas within an HTML page, it shows how basic geometric primitives combine to form a simple graphic. The code uses only native SVG elements and attributes—no external libraries—highlighting the bare-bones structure of SVG-based visualization.
